Reader Question: He Has A Girlfriend But Says He Loves Me, What The Hell Is Going On?

I’ve been seeing this guy for almost a year. It’s kinda a homie lover friend type thing I guess. I met him while in the process of breaking up with my now ex. Anyway, we have a great relationship, we get along great, we can talk about anything, and he’s always got my back and vice versa. Here’s the kicker: he’s got a girlfriend. He spends a lot of time at my house, I’ve met his kids, he’s met mine, he introduced me to a number of family members too. He told me he’s in love with me and I feel the same way. Here’s the problem: he’s still with his girlfriend. What the hell is going on here? We say I love you to each other all the time. He has a key to my house he spends a lot of time at my house.
